Pros
I appreciated how the company had several locations accross the US serving a variety of industries. A young technical person can pursue work opportunities in various places, with various options (operations, technical, project management, business, etc). I think their key involvement in the semiconductor industry is their biggest strength, as well as the core air separation businesses. Building on these areas are enough in my mind to give them a good business outlook.
Cons
They place a lot of focus on their “green” initiatives like hydrogen for mobility. I think they trying to sell governments and their on employees on technologies that have questionable feasibility relative to other “decarbonization” routes. The problem is that all they know how to do is process gases. And it can be challenging to imagine exciting areas of development when that is your whole focus. In addition, they seriously push young engineers into operations roles, because there is a scarcity of “plant engineers”. But those roles can be extremely frustrating. They often entail working at a years-old site with several recurring issues, putting patches on things rather than performing interesting engineering work. Documentation is often only found in dusty binders rather than in digital, searchable systems, making something as simple as looking up a technical drawing detective work. And the software tools were often outdated or non existent.
